I have a range of issues with Modela Player 4 that I can't seem to resolve:

(a) It's a bit crashy and often goes into 'Not Responding' mode. I have Win 7 and 4 Gb RAM on a reasonably fast laptop. Other software does not have such an issue with the meshes I'm using.

(b) It won't let me set up a tool with a diameter over 2.35 mm. I have the iModela from Techsoft, and one of the tools they sell is a 3mm ball cutter.
I would like to be able to use any diameter I want, up to 3mm.

(c) It won't let me directly set the cutting area in the Modeling Form dialog. I am trying to set the maximum area that the iModela can use, but it won't let me. I have to tinker with the margin and other settings before it will show a size within the allowable measurements. Perhaps the software should allow the user to set the size of cutting area first, and then all other measurements can be made after? This is a usability/logical workflow issue.

Please could anybody tell me if any of these issues can be resolved?

I have also been looking at Vectric Cut3D, which is excellent software and seems to be mostly there - it handles my models without crashing, and after tinkering, the on-screen render produces a good result. However, with that software it seems that the available post-processor that is compatible with the iModela cannot do a tool change. So...I haven't yet tried cutting anything with it (not wanting to waste any materials).
Does anybody out there know how to get this working properly with the iModela? Is there a different post-processor I could just slot in that would do the job?

All I'm trying to do is 2.5D cutting in JewelWax, in order to make jewellery. What are other people using to do the same thing?

(a) MP4 should be able to handle faily complex meshes, but remember it is a 32 bit software so possibly not as fast as the 64 bit softwares that are available.

(b) The iModela does limit the tool size as the 3mm collet is a modification we did here in the UK. To get arround this, you will need to download the MDX-40A or SRM-20 driver from the downloads page, and then select that as the machine, this will then take off the limit for the cutter size (just remember to reset the tool parameters and working area to iModela specifications).

(c) In modells player 4 it works out the size of the object, then puts in a margin for the tooling (and a slope if required) and then works out the total area that way. This saves time when cutting so you don't have to cut unnessasary material. If you wish to cut the whole block you will need to add the margins so the total area is cut.
